Obviously that latter setting won't work on sparc as there is no CLBYTES
definition (anymore).

It seems the better setting would be (which actualy compiles! :-):

    options 	BUFCACHE=10		# 10% of RAM

However it turns out that's probably not the problem I encountered.
This seems to be more along the lines of a real solution:

src/sys/arch/sparc/include/param.h:

- #define	NKMEMPAGES_MAX_DEFAULT	((6 * 1024 * 1024) >> PAGE_SHIFT)
+ #define	NKMEMPAGES_MAX_DEFAULT	((128 * 1024 * 1024) >> PAGE_SHIFT)

I've no idea why NKMEMPAGES_MAX_DEFAULT was the same as NKMEMPAGES_MIN_DEFAULT.
It would seem to be an excessively silly limitation.

I took the "128" from the similar definitions in the i386 variant....
